VOYAGER MIXER-OUT & EXT AUDIO INPUT Signal Levels

Someone can confirm what Voltage Peak-to-Peak is available at the Mix-OUT jack with only VCO 1 activated and mixer level at 5/10 ?

And then with the VCO’s 1+2+3 switched-on with their respectives mixer pots at 5 / 10.

I try to establish which is the nominal signal level for connecting external audio processors, a fact not provided in any document Moog Music I’ve ever seen.

There is also no known data on the EXTERNAL AUDIO INPUT nominal sensitivity. What range of levels is acceptable in Vpp, dBU, dBV, Vrms…, (anything would help the case).

Per the manual the External Audio Input can accept signals from instrument level up to line level. Input clipping is shown by the LED over the External Input pot in the mixer section.
